In said drawings, A, represents the frame of the machine, andB B the feed-table guides or supports, upon or along which the flat canbody blanks .1: are fed or moved by the l'OCll): rocating feed pawls or lingers U. pivoted atC" to the blank pusher-plates C on the rccipro- T eating feeder-slide U, the same being, for example, substantially similar in construction and operation to the correspondin, r feeder slide and pawis shown and described in the E. Jordan patent, No. 307,198, of October 28, 1884;, to which reference is here made.

I) and D are a pair of rocking and recipro-- eating hook-formers or edge-folders operating in conjunction with the clamping-jaws l) and D theu pper one, D of which is moved up and down by a vibrating yoke or lever D, actuated by acam w on the camshaft B. One of each pair of clampingjaws has a pro ecting lip (I, over which the hook or edge fold $1 is formed. The hook-former or edge-folder l) operates to turn its hook or edge fold down ward, while the corresponding hook-former which it is attached. Springs F actuate or or edge-folder D turns its hook or edge fold upward, as will be clearly understood from Fig. 9.

.which cam engages an antifriction-roller on a swinging yoke pivoted to the adjustable frame or carriage (V at di the head d of which yoke passes through a slot (Z in the rocking support d and engages the slide 05. Each of the heads 4 of the swinging yoke (1 has flat faces (1 at its sides, and rounded or curved faces (Z at front and rear to permit of the necessary rocking movement of the edgefolding tools D D. connection 4] with its rocking support (1 thus connecting the slide and support together while permitting the slide to reciprocate in respect to the support. The frames or carriages (Z are adjustable to and from each other on the main frame A to enable the machine to operate upon can-body. blanks of different lengths or to form edge folds thereon of different widths by an adjusting-screw d the same having, preferably, right and left threads (Z and which passes through nuts or threaded pieces d secured'to the adjustable frames or carriages (Z The cams r and r slide with the frames or carriages (Z on the shaft R, the cams having shoulders or collars engaging the frames or carriages. As the frames or carriages (Z carry the edge folding and clamping mechanisms, the adjustment of the frames or carriages to ,or from each other is all that is required to adjust the mechanism to the length of the blank and to the width of the edge fold required. The edge folder D is furnished with a gage D for the edge of the blank to abut against, said gage having an adjustable connection D? with the slide d and a spring D The spring D serves to hold the gage D in its retracted position.

E is the body-former horn, the same being furnished with two hinged or opening and closing wings E E, the wings being opened or expanded bya reciprocating Wedge E? in the horn.

F is avertically-reciprocating former Which operates to fold the flat blank downwardly around the horn, as illustrated in Figs. 15 and 19. The guides B, which support the flat blank :10, with the hooks or edge folds a," formed thereon, above the horn, are made movable or adapted to retract, so as not to in} terfere with the forming or folding of the blank downward around the horn.

F is a clamp for clasping the blank against the central portion of the horn, the same fitting in asuitable recessf in the former F and being provided with sliding guide-rods F to Each of the rocking and rec procat- 5 'ing hook-formers or edge-folders l) D, is

The slide (Z has a dovetail,

yieldingly extend this clamp-bar F in advance of the body-former F.

The body-formerF is removably secured to aslidef, which is reciprocated up and down in suitable guides f" on the frame of the machine by means of the toggle arms or links ff, the latter being on a lever f which is actuated from the dri ving-shaft S, through the connecting-link S, by a cam similar to that illustrated in Fig. 5 for operating the bumperslide G through the toggles g 5", lever g and connecting-link As the body-blanka, clamped against the V horn E by the clamp-bar F, is bent or folded downward around the horn by the former F, the movable guides B, which support the blank, are retracted or withdrawn by means of projectionsfon the body-former silde engaging cams or inclines f on the hinged armsf, which are pivotallyconneeted tolinks f upon which the movable guides or blades B are mounted through the adjustable connecting-barf. Springsf restore the guides or blades B to position. The vertical plate B of the guide is furnished with a slot b'to receive the horizontally-movable guide or blade B. A stop f limits the inward movement of the blade B.

F F are the horizontally-movable folders which bend the ends of the blank around the horn and cause the hooks or edge folds thereon to overlap and interlock as the wings of thehorn expandf Each of these folders F carries a tension or spring held sliding member F on its upper side,whichserves to-snugly wrap the blank around the born. The folder F and its sliding member F are mounted upon a reciprocating slide F, which is actuated by acam S on the driving-shaft S through the connecting-lever F and link F The sliding member F of each folder F is attached to reciprocating guide-rods F and is furnished with springs F.

After the hooks are lapped past each other, as illustrated in Fig. 20, the wings E E of the horn are opened or expanded by he wedge E and the hooks caused to interlock or engage each other, and then the vertically-reciprocating bumper or seam-squeezer (Jr com- Y body forward from the position where it is formed, and also a groove 6 on its under side to give room for theseam formed by the interlocking hooks m on the can-body (v The-can-body-forwarding fingers or pawls H. are actuated by reciprocating slides'H, to which they are connected zit/1 which slides H are attached by connecting-brackets H 5 with the slide iii-reciprocating on suitable guides ll, secured to the frame of the machine above the horn. The-slide H is reciprocated from the d living-shaft S through the connections l1. l4. A /4 The pair of reciproeating slides H on each side of the horn are also furnished with a series of can-l)ody-for'- warding pawls 71 pivot-ally connected thereto, and by which the can-bodies are intermittently advanced over the soldering mechanism by a I 5 step-by-step movement first to the fluxing device, next to the solder-applying device, and next to the sweating-iron, the can-bodies being supported and maintained in position by a can-body guide-horn M, preferably of a skeleton form, attached to the end of the bodyforme r horn E. The can-body guide-horn M is preferably composed of a series of small rods in, a pair of side bars in, having grooves m to receive the pawls h and a bottom bar m having'a guide-groove 121* to receive the seams oi the can-bodies, and thus maintain the seam centrally with the guide-horn to properly register with the tlux-a 'iplying device N, the solder-applying device 0, and the sweat- 0 W ing-iron P. 'J.hel'1ornrods m and bars m and m are all connected together by a cap m and spacer or connecting pieces m m, the cap wa being bolted or threaded to the end of the body-former horn.

3 5 N is the flux-applying device, the same consisting, preferablyptavertically-movable bar somewhat exceeding the can-body in length and furnished with a narrow wick or absorbent pad 21 on its upper grooved face, by means 4 of which. in connection with the flux bath or vessel N, the flux may be applied to the scam in the limited quantity required and'without smearing any unnecessary surface of the canbody on each side of the seam. The flux-applying bar N is carried upon a bent bar or yoke N carried upon the vertically-reciproeating slides N, which are connected together bya cross-bar N and moved up and down, as required, by a cam N on the shaft N which 5 is geared to the driving shaft S through the connecting gearing and mechanism a n? 151" w. 12. .12. 71 a n".

The solder-applying device or bar 0 some what exceeds the can-body in length and is provided with a small groove 0 in its upper face, by which a narrow line of solder is applied to the seam of the can-body when the same is stopped in position over the solderapplying bar. The solder-applying bar is moved up and down, as required, toimmerse it in the solder bath or vessel 0' and apply the solder to the can-body above by means of a vertically-movable bent bar or yoke 0", upon which the solder-applying bar is mounted and which is connected to the vertically-re 5 ciprocating slides 0", connected togetherby a cross-bar O and operated by a cam O on the shaft N. i i

The solder bath or vessel 0' is heated by burners O, and the flux bath or vessel N is also preferably heated by similar burners N The sweating-iron P is secured to a vertically-adjustable standard P, supported on a bracket P, attached to the frame. Burners P heatthesweatingdron. Neartheouter'end .75 of the can-body skeleton guide horn, M are beveled supp0rtingr0llers Q, the horn being furnished with cooperating rollers q, mounted on spacer m.

' The can-body-blankfeeder-slide C carrying the blank-feeding pawls or lingers C, is reciprocated as required by means of a cam S on the driving-shaft Sthroughlthe connecting mechanism C" C C O C The wedge E, by which the wings E of the S 5 horn are operated, is reciprocated required to open or expand the wings and permit the same to again contract by a cam S on the driving shaft through the connecting links and levers E E E In operation, the blanks being placed byhand or automatic feeding-mechanism on the guides B, the first pair of feed-pawls U advance the blank into register with the hookformers or edge-folding clamping-jaws D D, 5 and the edge-folders I) and l) are then operated, as illustrated in Figs. 9,10, 12, 13, and 14, to form oppositely-turned hooks or edge folds at the edges of the blank. The next reciproeating movement of the feeder-slide (J advances the blank over the horn it), and then the clamp-bar F clamps the same at its middle against the horn and the former l! folds vit downwardly around the horn... as illustrated in Fig. 19, the movable guides or blades B at this time retracting. The folders F F then close toward each other and complete the folding of the blank around the horn, illustrated in Fig. 20, and the horn is then ex panded to cause the hooks to interlock, and the seam-squeezer Gis then moved n p to compress the seam. The reciprocating can-body feeder-slides H through the action of the ingers H strip the can-body from the horn, and by their subsequent reciprocations advance it first to the fluxing device, then to the solder ing device, and then to the sweatingde'vice, and finally discharge it from the machine over the guide-horn M, it of course being understood that other can-b0d v blanks and can-bodies are at the same time being advanced step by step and operated upon by the successive devices. The adjusting-screw 1Z turnsloosely in the framework, and its right and left threads engaging the corresponding threads in the nuts or threaded pieces at, thus moves or adjusts the adjustable frames or carriages (Z to and from each other.
